伪正定泛函的矩问题

A moment problem for pseudo-positive definite functionals

Ognyan Kounchev, Hermann Render

AI总结:

针对一类称为伪正的带符号测度,提出矩问题,证明在合理限制下每个伪正定泛函存在表示伪正测度,并刻画等价表示测度类中的确定性,最后讨论截断矩问题。

摘要:

针对一类称为伪正的带符号测度,提出了矩问题。我们的主要结果表明,对于每个伪正定泛函(在合理的限制下),存在一个表示伪正测度。第二个主要结果是对等价伪正表示测度类中确定性的刻画。最后,讨论了相应的截断矩问题。

英文摘要:

A moment problem is presented for a class of signed measures which are termed pseudo-positive. Our main result says that for every pseudo-positive definite functional (subject to some reasonable restrictions) there exists a representing pseudo-positive measure. The second main result is a characterization of determinacy in the class of equivalent pseudo-positive representation measures. Finally the corresponding truncated moment problem is discussed.
